Function alloc_for_layout 

pub fn alloc_for_layout(layout: Layout) -> PtrUninit

Allocates memory for a layout, correctly handling zero-sized types.

For ZSTs (zero-sized types), returns a dangling but properly aligned pointer without actually allocating. This avoids undefined behavior since alloc::alloc::alloc with a zero-sized layout is UB.

Returns

A PtrUninit pointing to:

• Newly allocated memory for non-zero-sized layouts
• A dangling, aligned pointer for zero-sized layouts

Panics

Panics if allocation fails (calls handle_alloc_error).

Example

use core::alloc::Layout;
use facet_core::{alloc_for_layout, dealloc_for_layout};

let layout = Layout::new::<u32>();
let ptr = alloc_for_layout(layout);
// ... use ptr ...
unsafe { dealloc_for_layout(ptr.assume_init(), layout); }
